I read an article about Megan Fox's deformed thumbs today in a newspaper, which cited the attention that has been brought to it on the interwebs.
It's about time people started taking me seriously.

The best way to put the question, which I heard only the other day, is "Can I see you?".
Just be genuine, and if she turns you down* don't be awkward about it, just go straight back into friend mode.
*Let's be realistic, she will probably turn you down. If she wanted you, she'd have given you signals out the wazoo.
